Introduction
The the 90DM series of Infrared CO2 Gas Monitors are available with two different configurations, for wall mount or duct mounting. These sensors are ideally suited for commercial or industrial gas detection application. Both enclosures are made of ABS plastic, offering maximum durability.

Wall Mounting
The SM Model is a wall-mounted unit with a compact and an aesthetically pleasing design which blends perfectly and discretely with any room decor. Easily installed directly onto drywall or other surfaces, the SM Model allows for superior gas circulation and airflow.

Duct Mounting
The DT Model is designed to accurately detect the presence of CO2 in air-handling systems. Unlike other units on the market today, the enclosure is totally airtight, more compact, and extremely lightweight, with a convenient mounting bracket to improve installation. All in all, its superior operational and cost efficiency make the DT Model the ideal choice for larger-scale CO2 detection applications.
